补充资料:包钢无缝钢管收集装置降噪和防冲击研究
包钢无缝钢管厂作为国家大型骨干企业,面临着激烈的市场竞争,因此在保有原有优势的基础上,迫切需要全面提升产品的质量,争取更大的市场份额。包钢无缝钢管厂的设备是五十年代从前苏联引进的,主要生产直径140mm至直径426mm的无缝钢管。在收集过程中,钢管的落差大,产生了噪音和冲击 。冲击使钢管发生了塑性变形,噪音损害了工人的身体健康。作为面向二十一世纪的现代化企业,必须考虑如何在优质高效生产的前提下,创造一个清洁、无污染的生产环境。因此,对于无缝钢管收集装置的深入研究势在必行。 | ||

使用ANSYS软件进行无缝钢管的变形模拟,其数据真实性得到了现场的认可,且在获得数据的同时并未影响生产。模拟的最终结果为新型无缝钢管收集装置的设计提供了理论依据,目前依据这一模拟结果设计的第一种方案已完成,正在进行第二种方案的设计。 | ||
